Figure 2 Brain natriuretic peptide (BNP) and N-terminal BNP (N-BNP) results from five different assays in 112 patients with no heart failure (open bars), 23 patients with no heart failure but significant left ventricular systolic dysfunction or left-sided valvular disease (striped bars), and 70 patients with congestive heart failure (dotted bars). By all assays, results from the group with significant left ventricular dysfunction or left-sided valvular disease and no heart failure were significantly higher than those without heart failure and significantly less than those with heart failure (p < 0.01 for all comparisons). Biosite = Biosite point-of-care BNP assay; Clinical = local clinical BNP assay; Research = local research BNP assay; Roche = Roche N-BNP assay; Local = local N-BNP assay. Bars indicate median value and interquartile range, lines represent 10th and 90th percentile values, dots represent outlying values.
